Finder cannot preview prores files.

Re the thumbnails, open View Options for the folder holding the docs - with the folder open, press Command-J or select Show View Options from the View menu. In the View Options screen, checkmark the item "Show item preview".

The Desktop counts as a folder for this purpose.

I have the same problem. Professional video editor, been using Snow Leopard since it came out, never had a problem previewing or "quick-looking" ProRes Quicktime files within the Finder, but as soon as I upgraded to Lion this function no longer worked.

I read in another thread that re-installing Lion fixed this problem, but a new install on my machine failed to restore ProRes Finder preview functionality.

Thought that maybe Lion was hoarding RAM, so I upgraded my 4GB on my MacBook Pro to the maximum 8GB. Still doesn't work.

Anyone else having this problem?

Any solutions?

Try a test on one of the files.

After making sure the folder it is in has its View Options set to Show Icon Preview, select one of the files and do a Get Info (Command-I) on it. Click the icon in the upper left of the Get Info window. Then see if Clear is available in the Edit menu. If it is, select it.

Lion does not handle some program-generated previews well. By clearing such an item, which the above action accomplishes, it makes way for Finder to use its function to show a thumbnail.

The problem isn't the file's icon, which is clearly visible (in this case a Quicktime movie icon), it's the ability to view it by pressing the spacebar while in the Finder (what is commonly referred to as "Quick Look" - same as in Mail).

This problem only occurs with ProRes files; all other Quicktime formats Quick Look in the Finder just fine. ProRes used to as well in Snow Leopard and all previous versions of OS X, it's only since upgrading to Lion that this no longer works.

It's worth adding that the ProRes Quicktime component is still in the Quicktime folder in the Library, and ProRes files still open in Quicktime 7, Quicktime X, Final Cut Pro Studio 3, and iTunes.

Any thoughts?

Thanks,

I can't see either. Very annoying, I depend on quickview all the time to find the files I need. I keep thinking that my transcodes are failing.

Any help would be great. Has Apple commented?

I'm actually having the same issue, but only since I've updated to Moutain Lion. I run a video production company and I have 19 brand new iMacs all with the same issue. Below is an example of how the Apple Prores 422 file is as an icon, in the Info window and in QuickLook. The movie plays back fine in Quicktime 10 and the file was created in FCPX. Even files from FCP7 do the same.

This slows down production when searching though files. Please help.

I'm experiencing this too, I've got all the relevant codecs in the ~/Library/Quicktime folder but still can't use quicklook on any ProRes files.

Hi all,

I'm the original poster and I finally figured it out: a little Div-X app I had on my computer was the culprit. Once I deleted that the preview powers of the Finder were fully restored.

The catch is that I figured this out a while ago and forgot what the name of the app was. But I do know it was Div-X related for sure, and that I hardly ever used it (thus not knowing its name) and I certainly don't miss it.

So I'd advise you try tossing any / all non-native video applications and see if that does the trick. Worked for me!

Hmmm thanks for the update, no such luck for me. I deleted every other compontent in that folder except the stock apple ones and still nothing.

Do your systems have FCS7 installed?

Thanks

After much hesitation, I re-installed Mountain Lion on one of my iMacs. It only took an hour and I didn't have to delete or re-install anything elae over. I will the 18 other iMacs I have next week.

Hi Bill,

This got it working again?

Did the reinstall restore you to a fresh system or did it retain settings/files and just update system files?

Thanks

Here's the steps: I redownload Mountain Lion from the App Store and then when it got done, I double clicked on it and it reinstalled with deleting any of my apps or settings.

When I tried to reinstall Lion I still had the same problem. Same goes with a reinstall of FCP7. Only deleting the Div-X app remedied the problem for me.

For what it's worth, we've got seven more editing systems running that didn't have this problem when upgrading to Lion. None of them had any Div-X apps on them...

I finally got around to reinstalling Mountain Lion and it worked for me. Happy times

Thanks
